Specification of Letters Patent.

atented Feb. 23, 1909.

Application led November 23, 1908. Serial No. 464,067.

To all whom. it may concern:

Be it known that l, EDWAiin B. BAnNiiiLL, b v means o'l a coupling sleeve 1.3. Marion, in the county oi (ii-ant and State of 1 wiso secured a cross-head 1S into the outer Fluo-Cleaner, of which the 'following is a specii a citizen of the United States, residing at Indiana, have invented a new and useful iication. .I

.This invention relates to a device for re moving accumulations of soot, dirt, etc., from boiler fhies by a blast of steam. Such devices are provided with a. nozzle for direct ing blasts to the fines, and the present invention relates more particularly to such a nozzle, its object being to provide a nozzle which is simple in structure, and inexpensive to manufacture.

A further object of the invention is to provide improved` means for operating and adjusting the nozzle so that each and ever) thie may be reached, thus assuringr a thorough cleaning of the boiler.

The invention also has for its object to provide a cleaner of this kind which is eionoinical in its use of'steani. n

duced scale.

In thel drawings 5 denotes a tube ywhich is open at both ends, and screw-threaded eX- 'terioily to receive caps (i and 7, respectively. rlhel cap t5 has a. bore S in which is mounted a series of nozzles 9 projecting froin a body iortion 10 rotatably fitting in said bore. 'l hrcc nozzles are shown, and they arc inclined with rcs )ect to the axis of the dcvice, so that the lblasts will 'be deflected laterally. The bores of thc nozzles coininunicate. with steam ports 1 1 in tho body portion 1t), and on the. inner end ofthe latter is seated a valve for controlling Asaid ports. 'lhis valve-is in the shape of a disk 12 having,r in its peri )hery a notch Vor recess 13 which is adap'tcd to be. brought into aliiicinent with any of the ports 11, whereby the nozzles may be successively brought into play, when the disk is rotated. 'lhe valve is operated b v a stein 14 secu red thereto, and cxtcndircr therethrough and a short distance from the face of theviilve dish and seatingr in a recess 'made in the. inner face of the part 1t), whereby said disk is centered on its seat.

Inside thetube 5, and spaced therefrom, is

located a tube 1G which is open at its ends,

and is connected at one end to the part 10,

To the other end ol` the tube l() is screwed or other end of which is screwed a tubular stein 19 The stein 1t) priijects l'roni the head 7 and has its projecting end i'ittcd with a hand wheel 20. T he head T is provided with the packing nut '21 through which the stein 19 passes, and around which, within the nut, a suitable )aching 22 is placed. T he stein 19 projects )evond the hand wheel 2l), and is also )rovidcd with a packing nut 28 through whicli the valve stein l-r extends, a suitable packing 24 being placed around said stein inside.. the packing nut 33. The valve stein 14 projects a short distance beyond the packing nut 23, and on said projecting end `is secured by means of a set-screw 25, or other suitable ineans, a laterally projecting arm 26, having secured to its outer end, a tlat spring 27 which is engaeeablc with notches L S inade in the riin of thenintl wheel 20, for a purpose to -be presently descril'ied. The head 7 has inlets 2Q and is also tit-ted with a drip cock 30. 'lhc steam passes from thc inlets past the cross-head 1S, into the tube lo, and then to the nozzle for which thc valve is set. Be-

tween thc tubes 5 und lt' is interposed a valve isprevented l'roin hein,er pulled ofi` its seat.

'lho construction hcrcin described porniits the nozzles to bc rotated by the hand whccl 20, and the valvc cont rollingT thc ports to said nozzles, is operated by the arm 26 on the valve stein 111-. Upon rotating,r the hand whccl, a circle ot lhics within the rangc ofthe nozzle which is dischargin;r is closed. To bring; the next nozzle. into play. the siring 27 is raised out ol the notch '29, and the valve srin is turned until said sprintr enters the. next notch. 'lhis brinp's the notch 13 of thc valve dish in liuc. with the port of the next nozzle. after which the hand whccl is again i'olalcd to blow thc next circh` ol`^ ilues within the radius ol` said nozzle, and so on `,until all the lhics arc clcancd.

l`lic hand whccl is lurucd one or inorc tiincs to each nozzle accordiupr to thc ainounl ol soot and 11o dirt in the iues. The valve, turns with the nozzle, by reason of the engagement of the ring 27 with the notches 28`of the Vhand Wheel, in order that the nozzle which happens -to be discharging may remain open 'of fines, and directs the steamsquarely thereto Without any Waste of its energy.-I

Althoughlhave shown. and described three nozzles, it Will be understood, that their number may be varied, and minor changes not involving a departure from the inventive 'i idea may also` be resorted to.

- device Will be suitably located .inthe rear-.Wall of theboilerl furnace,` the hand 'i parts be' on the outside thereof. Steam' 'lssuplie to the inlets 29 hiya suitable --connection with the bo'ger.
